Specification ofLetters Patent. Patented Apr, 11, 1916.

Application filed July 22, 1915. Serial No. 41,278.

To all whom it may concern:

Be it known that I, ALFRED J. STECKER, a

citizen of the United States of America, residing'at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Attachable Brushes for Vacuum Cleaning- Tools, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates more particularly to that type of vacuum cleaning apparatus in which the suction tool is directly connect-,

ed to the motor and fan casing, and it is theobject of the invention to provide means for quickly: attaching or detaching a. brush in relation to the mouth of the tool.

For remo-ving dust from carpets, rugs and other fabrics, the most effective tool 'is one having an openslot arranged in proximity to the surface to be cleaned. Such a construction is not as well adapted for the removal of dust from a floor or other impervious surface, nor would it always be effective in detaching lint or other adhering matter from a fabric. On the other hand where the tool is provided with a brush this will operate to dislodge adhering dirt, but .is easily clogged when used generally for cleaning.

It is the object of the present invention to provide means for quickly converting the one type of tool to the other, this being particularly advantageous in machines having permanently attached suction tools.

To this end the invention comprises the construction as hereinafter set forth.

In the drawings: Figure 1 is a sectional elevation of a vacuum cleaner to which my improvement is applied; Fig. 2 is a'perspective viewv of the suction tool with the. brush removed; and Fig. 3 is a similar view show-- ing the detached brush. I

A is the motor and fan casing, and B is the suction tool permanently attached thereto and having the elongated slotted mouth portion C. As shown, this is normally supported by rolls D at its opposite ends, so as to extend in proximity to the surface to be cleaned. For converting this tool into one of the-brush type, I have provided an attachable brush E, preferably comprising parallel side bars F and'F, each provided with depending bristles G. The bars F and F are connected to each other by cross bars H and H at opposite ends thereof, which are so fashioned as'to embrace the mouth portion of the tool and to hold the bristles ad acent to the longitudinal edges thereof. For securing the brush to the .tool the latter is preferablv provided with ribs I, and the cross bars H and H are bent to hook over the rib on one side as indicated at J. On the opposite side there is arranged a spring catchKfor engaging with the rib which will yield when the brush is pressed into engagement and will then snap into a retaining position.

With'the construction described, when it is desired to attach the brush, this may be quickly applied and the tool operated in the usual manner of brush tools. The engagement is such that in ordinary use the'b'rush will not become accidentally detached, but

' ing end cross-bars for embracing and detachably engaging the nozzle.

3. A detachable brush for vacuum cleaning tools, comprising parallel brush bars, end cross bars bent to embrace the mouth of the tool, and yieldable catches for securing said bent cross bars to the tool.

4. In a detachable brush for vacuum clean-. -ing tools, a brush bar, members projecting from the respective extremities of the brush bar bent to embrace the mouth of the tool, and yieldable catches respectively carried by said members for securing said bent members tothe tool.

5. In a detachable brush for Vacuum cleaning tools, parallel brush bars, a connection between sald bars engageable with the mouthof the tool, and a yieldable catch mounted mwepee upon the connection to detachably secure the same to the tool.

In testimony whereof I afiix my signature in presence of two Witnesses.
